Title: Simulation Study on Drainage of Oil by Alternative Water and Natural Gas after Water Flooding in Block Lu 2
Abstract: The deep heavy oil reservoirs with edge and bottom water of Block Lu 2 of Lukeqin Oilfield of Tuha are under development stage with high water cut.The depth of 2 300 m,highly viscous oil and high reservoir pressure result in large heat loss in thermal recovery and difficult recovery of the reservoirs.A simulation study on the alternation drainage by water and natural gas is carried out based on deep investigation of enhanced oil recovery by gas injection after water flooding and the reservoir characteristics after water flooding.The study establishes typical geology model;conducts simulation optimization of main effect factors of alternative drainage by water and natural gas;predicts production gain of the reservoirs;and provides theoretical bases for further development of the reservoirs.
